Video: Detroit Speed/Arrington Performance ’69 Charger Overpowers Dyno


Some car builders are just superior to others. It’s not hard to come to this conclusion after spending a few minutes perusing the massive build journal of the “Mayhem Charger” over at Detroit Speed’s on-going project page. This machine has been meticulously reworked – and we mean we can’t find one square foot that is “bone stock.” Built by Detroit Speed and powered by an Arrington Performance 426 stoker Gen III Hemi topped with a custom 4.0-liter Whipple Superchargers supercharger setup, is by no means a restoration in any form.

The blown Arrington Hemi is backed by a Bowler-built automatic transmission rowed by a custom one-off hand-carved woodgrain pistol grip shifter. Although the hood, fenders and front clip are absent, this ’69 Charger R/T is still an absolutely gorgeous piece of craftsmanship (seriously, click on the first hyperlink to view the photo gallery – it’s amazing). The rear lights are modern LEDs, the trailing tail lip has been extended, the exhaust outlets are billet one-offs exiting out of an extended fascia…the list goes on and on.


And being that it is being built by the master autocross racers at Detroit Speed, this Charger is guaranteed to perform as good or better than it looks. As Detroit Speed notes, “This will be a full rebuild utilizing the Detroit Speed X-Gen Front Frame and a custom built version of the Detroit QUADRALink™ that will pieces from our various QUADRALink™ product line.” The savvier observer will notice carbon fiber front disc brakes, as a whole lot of DynaMat insulation beneath a tucked-away aftermarket air conditioning system and full Holley Terminator EFI hardware.

We don’t have confirmation on how much power the stroked Gen III Hemi made either on the engine dyno or on the rollers of the chassis dyno, but watching it nearly break loose will tell ya, it’s no mere street cruiser.
